Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a closure element or a connecting element for decorative chains, in particular pearl chains.

(Prior Art) Consists of a plug-in bushing that is open on both sides and surrounds a coil spring, into which a head plug with longitudinal grooves curved from both sides resists the spring force of the coil spring. A closure member of the type that is pluggable and can be locked in bayonet closure fashion with the internal projection of the plug-in bushing by rotation of its axis is known from Swiss Patent No. 608,703.

(Problems to be Solved by the Invention) It is an object of the present invention to utilize the modification possibilities of this known 1371M1 member for use in multiple chains and/or
It is enhanced by configuring the chain to combine with ornaments.

(Means for solving the problem) A measure of the invention for solving the above-mentioned problem is that the plug-in bushing is divided on one side into a plurality of head plug receptacles.

Embodiments In the device described above, the only receiving part contains a continuous coil spring with one end plate on each side. The coil spring of the lid or receiver is supported only on one side in the end plate and on the other side at the bottom of the blind hole forming the receiver. In other embodiments, each receptacle contains a coil spring in the arrangement. Said receptacle with a common consistent coil spring is divided by a wall into two aligned blind holes, each of which accommodates two coil springs with one end plate. There is.

Advantageously, the axis of the receiving cylinder is bent in such a way that the end plate lies at right angles to the axis of the cylinder.

In order to fasten the closing element to an ornament or the like, according to the invention, the ornament has two angled connecting elements, one of which projects into the receptacle against a spring force; In addition, the other angled connecting member projects into a recess in a projection provided on the outside of the plug-in bushing.

The connection between the ornament and the bushing can also be achieved by attaching to the ornament a coupling member which holds one or more head plugs as described above.

Embodiment According to FIG. 1, a coil spring 2 is supported in a receiving part 11 of a bushing 3. The coil spring has two end plates on both sides.
It is supported at 0.20°.

Alternatively, the receiving part 11 may be separated by a wall 40, in which case two blind holes 11, 11a are present,
Two springs 2, 2a are arranged in this. End plate 20.
20' rests on the outside against a projection 21.21° of the inner wall. The head plug 2222' can be inserted into the bushing 3 from both sides. The projection 21.21' then slides into the curved groove 23.23°. When rotated U, the protrusion enters the curved portion of the groove 23.23°.

As a result, for example, the end pearl 7.degree. 7.degree. of the chain is fixed to the bushing 3. This closure can be released again by pushing the head plug in again and rotating it in the opposite direction.

The bushing 3 has an integral projection 35 with an axis-parallel notch 24 for fixing the bushing 3 to the decoration 30. According to FIGS. 8 and 9, the decoration has two angled connecting pieces 31, 32. Angle connection member 3
1 into the bushing 3 (FIG. 8), so that the bushing 3 can be swiveled into a horizontal position and the recess 24 can be placed in the direction of the angle connecting member 32. Then bush 3
When released, the angle connecting member 32 projects into the recess 24 and fixes the bushing 3 to the decoration 30. However, according to FIG. 10, this fixing can also be effected by covering the decoration 33 with a single-shaped holder 34 with a head plug 22.22°.

FIGS. 2 and 3 show two (FIG. 2) or three (FIG. 3) receivers 11, 11', 11'' which are grouped together and fan out on one side. One receptor (
Only 11) can be inserted from both sides. Second
In the figure, it is the lower receiving part, and in FIG. 3, it is the central receiving part.

The axis of the receiving part 11 in FIG. 2 is curved, so that the end plate 20 lies at right angles to the axis of the cylinder.

In Figure 2, the protrusion on the right tube end is marked 21°.

21°°, and the end plates are designated 20', 20''.
and an end plate 20"', and the lower tube end has a projection 21"' and an end plate 20"'.

FIG. 4 shows a coupling member with two closing heads 22.22° on each side.

In FIG. 5, the terminal pearl or ornament portion 25 is shown. A large number of variants can be achieved with this closure part by simply inserting it.

FIG. 6 shows two of the bifurcated closures of FIG. 2, each of which complements two ends of a double pearl chain 70 together. These lids or closure members can be closed together by means of a connecting member according to FIG. Instead of using a simple binding member, a decorative set comprising a bottle 27 and a jewel 26, shown in the lower central part of FIG. 6, may be used.

FIG. 7 shows an ornamental formation (Schmuckbildn).
The coupling member according to FIG. 2 is shown processed as er) 29. It is decorated with three diamonds 36. The head plug may be a double-head plug according to FIG.
It may be integrated with
